Gerard Butler reveals who is the better kisser: Jennifer Aniston or Angelina Jolie?

On Watch What Happens Live, Gerard Butler was forced to pick a side when host Andy Cohen asked him a question that really only Brad Pitt can answer. "Gerard Butler, you have kissed both Angelina Jolie and Jennifer Aniston on screen. Who is the better kisser?"

While playing Cohen's "Plead the Fifth" game, in which the guest is only allowed to "plead the fifth" to one of three uncomfortable questions, the 300 star immediately rejected the idea of having to answer such an awkward question. Unfortunately for Butler, he had already pleaded the fifth to the first question, "Name one movie you did strictly for the paycheck."

But back to the main question at hand. Cohen's other guest, and Butler's Den of Thieves co-star, Curtis "50 Cent" Jackson even chimed in saying, "No. We need to know this," before Butler finally made his decision, saying "Um...Jennifer Aniston." The audience cheered to Butler's response, while 50 Cent was also pleased, as he said, "No, no. This is good. This is good stuff." However, choosing sides wasn't the only awkward question Butler had to answer. One caller asked the actor about the craziest place he has ever had sex.

"I'm trying to think because I've had sex in some crazy places," said Butler. "I had sex on the side of a volcano once. That was pretty cool. Actually, it was pretty hot. Um, and on a glacier." Cohen pointed out to Butler that he seemed to enjoy hooking up in temperate climates, but Butler quickly clarified that it's more about making a story more interesting. When 50 Cent asked Butler what motivated him to have sex on a glacier, Butler hilariously answered, "The fact that I was on a glacier. I'm like, 'Hey, wouldn't it be kinda awesome if we had sex?' I gotta be honest, it was not fun. My ass stuck to the ice." Sounds… cool?
